METAL VAPOR RECTIFI'ER.

Application filed May 31, 1922, Serial Not 564,926, and in SwitzerlandJune 11, 1921.

' casings extends into a zone of the interior of the rectifier vesselwhich is highly saturated with metal vapor.

In the case of a small load, or if an anode is cut out, it may readilyoccur that the 10 metal vapor cond'enses on the anode because thepressure in the interior of the anode casing is higher than in the upperpart of the rectifier vessel and the temperature of the anode maybe toolow.

In order to prevent condensation on the anode according to the presentinvention the anode casing is provided, inaddition to the openingsforthe are, at its lower end, with at least one lateral opening whichleads to a strongly cooled point of the rectifier vessel either directlyor by way-of an attached pipe. The Vapor-will then flow from thecasingto the said cooled point, and condensation on the anode will notso readily occur.

One embodiment of this invention is illustrated by Way of example in theaccompanying drawing which shows diagrammatically a section of arectifier vessel.

As shown, the anode casing a is placed by means of the rum 1) 1ncommunication-3o with the cooled wall of the condensing chamher 0.

-What I claim is v 1. A metal vapor rectifier including a cooled mainvessel having a strongly cooled 5 part, an anode and an anode casingopen at its lower end and perforated near its' upper end at a pointadjacent to said strong- 1y cooled part of said rectifier vessel.

2. A metal'vapor rectifier as claimed in 40 claim 1, including a pipe orduct leading from said perforated upper end of said anode casing tosaidstrongly cooled. partof the rectifier vessel.

3. A metal vapor rectifier as claimed in claim 1, including a pipe orduct leading from said perforated upper end of said an. ode casing tosaid strongly cooled part of the rectifier vessel, said strongly cooledpart being constructed as an extended portion of the main cooledrectifier vessel.

In testimony whereof I have signed my name to this specification.
